High Purity Materials

American Elements specializes in manufacturing high purity and ultra high purity materials ranging from 99.999% (5N), 99.9999% (6N), 99.99995% (6N5), and in some cases up to 99.99999% (7N) and 99.999999% (8N), such as 8N gallium ingots and 8N mercury metal. We can produce materials to specific grades including UP/UHP, semiconductor, electronic, deposition, fiber optic, and MBE grades.

Purity

The high standard and good reproducibility required of the purity profile method is clearly evident from that perspective. There are some other tests that also contribute to the general impression of the quality of a substance, i.e., tests for protolytic impurities, content of chloride, sulfated ash or residue upon ignition that gives the inorganic content.

Orbital welding

Owing to its ability to realise high purity results, orbital welding found its place in the production of clean-room components for the semiconductor industry. Its application has now expanded to the construction of pipework and equipment for diverse industries like food processing, pharmaceuticals, chemical engineering, automotive engineering, biotechnology, shipbuilding and aerospace.
